Is a genocide unfolding in South Africa?

According to US President Donald Trump, white South Africans are fleeing what he terms a genocidal threat.

This assertion formed the basis of a controversial policy shift that has enabled expedited refugee resettlement to the US for white South African farmers.

Genocide, under international law and the Genocide Convention of 1948, refers to the deliberate and systematic destruction of a national, ethnic, racial or religious group.
